Samsung's success makes it a target for Nokia, HTC marketers

Samsung's success in climbing to second place in the U.S. smartphone market has landed it in the cross hairs of competitive marketers. A spot from Microsoft and Nokia compares the camera of the Windows-powered Nokia Lumia 920 with Samsung's Galaxy S III, and HTC is also taking aim at the Galaxy S4 as it rolls out the HTC One. BlackBerry, on the other hand, doesn't "compare ourselves to the other options on the market," said Chief Marketing Officer Frank Boulben.
